Compositions for the treatment of pilosebaceous gland inflammations comprising aluminium fluoride

ABSTRACT

The present invention relates to compositions for the treatment of pilosebaceous gland inflammations, especially of the hair follicle and its appendages, in particular of Acne Vulgaris and Folliculitis, comprising as active ingredient AIF or chemical compounds which finally release AIF, or combinations of aluminium and fluoride salts which finally release AIF. AIF in accordance with the present invention relates to Aluminium fluoride (Aluminium Trifluoride; Aluminum Fluoride), CAS No 7784-18-1, EINECS No. 232-051-1, having an empirical formula of AIF 3 . Said compositions have, inter alia, pharmaceutical, cosmetic or quasi-cosmetic properties. The present invention also relates to the use of said compositions in said treatment, and to methods for the treatment of pilosebaceous gland inflammations with said compositions.

[0001] The present invention relates to compositions for the treatment of pilosebaceous gland inflammations, especially of the hair follicle and its appendages, in particular of Acne Vulgaris and Folliculitis. Said compositions have, inter alia, pharmaceutical, cosmetic or quasi-cosmetic properties. The present invention also relates to the use of said compositions in said treatment; and to methods for the treatment of pilosebaceous gland inflammations with said compositions.

[0002] The present invention will be illustrated herein in particular with reference to Acne Vulgaris and Folliculitis but is not restricted to these pilosebaceous gland inflammations.

[0003] The pathophysiology of Acne Vulgaris is multifactorial. It involves a genetic tendency of the hair infundibulum to narrow resulting in a keratin plug formation in the sebaceous gland ductuli. This is accompanied, in part of the subjects, by an androgenic-related sebum hypersecretion, causing noninflammatory lesions, i.e. closed and open comedos. Concomitantly, some of the lesions evolve into an inflammatory process, triggered in part by free fatty acids release into the dermis, together with a secondary microbial colonization of the pilosebaceous unit. The overall inflammatory and noninflammatory lesions are defined as Acne Vulgaris. The inflammatory lesions are responsible for the long lasting cosmetically disfiguring scars.

[0004] It has been amply described in the past (Fitzpatrick et al., Dermatology in Internal Medicine, McGraw Hill, In, 4th Edition, 1993) that Acne Vulgaris might be exacerbated by exposure to or intake of various chemicals and molecules, such as mechanical pressure, foods, drugs, halogens, tars, cosmetics and aluminium fluoride-containing toothpastes (Epstein E. Arch. Dermatol Fluoride toothpastes as a cause of acne-like eruptions, 1976 July, 112(7):10334). An inflammatory process is responsible for the classical clinical signs, such as papules (elevated palpable red areas) and pustules.

[0005] A process similar to inflammatory acne is Folliculitis, an “inflammation of a follicle or follicles.” (Dorland's Illustrated Medical Dictionary, WB Saunders Comp., 27th Edition, 1988). It results from a microbial colonization and infection of the hair follicle shaft. Folliculitis is commonly accompanied by a perifollicular inflammation, perceived as classical inflammation signs of redness, swelling and tenderness at the basis of the hair shaft. More severe cases appear as significant perifollicular inflammation, named furuncle, carbuncles, impetigo, etc. The clinical picture of an inflammatory acne lesion and Folliculitis are identical, and Folliculitis is part of the acne pathophysiology. Mechanical trauma may induce or aggravate Folliculitis as well. However, a basic difference delineates these two entities: 1) The areas of distribution of the lesions in acne are seborrheic (e.g. face, chest, upper back), unlike Folliculitis, which manifests itself on seborrheic and non-seborrheic body areas and 2) Folliculitis is not related to genetic predisposition and hormonal changes.

[0006] From a practical point of view the treatment is alike: anti-inflammatories in conjunction with anti-microbials are started in mild cases as topicals. A more severe spread or degree of lesions require a combined systemic treatment. Agents which change the pilosebaceous unit function, such as retinoids, are sometimes used in Acne Vulgaris and stubborn Folliculitis (barbae). Control of Acne Vulgaris, specifically, requires the additional use of classical drugs, such as astringents, sulfur and benzoyl peroxide.

[0007] As will be detailed below, current treatment of Acne Vulgaris and Folliculitis is either largely ineffective or involves chronic systemic administration of drugs that cause numerous undesirable side-effects. Hence, it has been desired in the art to provide an effective and convincing treatment for both entities. A definitive highly efficacious, fast acting and low side effects solution is lacking. Various compositions are known in the art for controlling these pilosebaceous related disorders and due to lack of efficacy of single compounds physicians are compelled to use combined treatments (Krowchuk DP. Treating Acne—A practical guide. Medical Clinics of North America, 2000;84) from the list mentioned beneath.

[0008] Some of the ingredients useful in said treatments are categorized hereinafter by their postulated mode of action. However, it is to be understood that in some instances these ingredients operate via more than one mode of action.

[0009] Therefore, the following classifications are made herein for the sake of convenience only and are given by way of example and do not limit the ingredients to the particular application or applications indicated:

[0010] a. Topical antimicrobials such as clindamycin, tetracycline, erythromycin—having low efficacy;

[0011] b. Antimicrobials systemic class such as minocycline, clindamycin, cephalosporin, sulfur-trimethoprim—causing drug rashes and antibiotic resistance;

[0012] c. Antimicrobial and radical free generating benzoyl peroxide having low efficacy;

[0013] d. Mild steroids (in severe cases applied by way of intralesional injection)—suitable for short term treatment only, but aggravating Acne on prolonged use;

[0014] e. Classical undefined topicals such as sulfur, zinc, resorcin, salicylic acid—having low efficacy;

[0015] f. Astringents such as aluminium chloride, resorcin—inefficient and causing pruritus;

[0016] g. Topical retinoids such as natural and/or synthetic analogs of Vitamin A or retinol-like compounds which possess the biological activity of Vitamin A in the skin as well as the geometric isomers and stereoisomers of these compounds—causing photosensitivity, are slow acting and irritating;

[0017] h. Systemic (isotretinoin) retinoids—drugs with high cost, relatively high efficacy, having numerous side effects such as 100% dryness, 90% photosensitivity, 30% hair loss, 15% musculo-skeletal pains, 5% liver function disorder, and lately reported depression induction and teratogenicity;

[0018] i. Contraceptives—having all known side effects, from hyperlipidemia to pulmonary emboli, and are slow acting (require months of use);

[0019] j. Others: azelaic acid—having low efficacy; and

[0020] k. Plant extracts—scientifically non-defined as active.

[0021] A mild clinical case of Acne Vulgaris or Folliculitis is usually treated at the start by two different topicals, such as an anti-microbial and benzoyl peroxide. Mild steroids might be added. A subject suffering from a moderate condition may need the addition of a systemic antibiotic, with its obvious side effects. Topical retinoids may be added alternatively. Severe causes are generally treated by the oral isotretinoin. Due to the reluctance of the disease and to patients—derived pressures, some of the physicians are compelled to prescribe high side effect oral isotretinoin (35% incidence of severe side effects; Strauss J S et al, J Am Acad Dermatol, 2001; 45:196-207) even in patients sufferring from a mild Acne Vulgaris.

[0022] There thus remains a need to provide improved topical compositions for treating inflammatory pilosebaceous disorders. There is a particular need to provide compositions and methods useful against lesions of Acne Vulgaris and of Folliculitis which:

[0023] (i) Improve rapidly the pilosebaceous inflammation;

[0024] (ii) Can be used topically or systemically;

[0025] (iii) Are available to women without causing teratogenicity; and

[0026] (iv) Are devoid of oral antibiotic or retinoid side effects.

[0027] Aluminium fluoride (Aluminium Trifluoride; Aluminum Fluoride), CAS No 7784-18-1, EINECS No. 232-051-1, having an empirical formula of AIF₃, (hereinafter called “AIF”) is an inorganic salt approved for use as an oral care agent, i.e. as “a cosmetic ingredient and excipient used in products to polish teeth, act as oral deodorant or provide other cosmetic effects.” (International Cosmetic Ingredient Dictionary and Handbook, Wenninger et al., The Cosmetic, Toiletry and Fragrance Association 8th Edition, 2000). In addition said compound is used in ceramics, as flux in metallurgy; in aluminium manufacture, as inhibitor of fermentation; and as a catalyst in organic reactions.(Merck Index, 1996)

[0028] It has now surprisingly been found that aluminium fluoride (AIF), or chemical compounds which finally release AIF, or combinations of aluminium and fluoride salts which finally release AIF, which are applied as a topical component on inflammatory lesions of Acne Vulgaris and Folliculitis causes an improvement of the lesions. A search of the literature did not reveal any reference to AIF activity on sebocytes or to a therapeutic effect of AIF on pilosebaceous inflammation, but on the contrary to adverse effects induced, for example, by fluoride toothpastes which induce Acne Vulgaris (Arch. Dermatol. Saunders M A, 1975, 111:793).

[0029] It is the object of the present invention to provide compositions, mostly topical, for controlling inflammation of the pilosebaceous gland. It is a further object of this invention to provide methods for controlling inflammation of the pilosebaceous gland.

[0030] Because of the ability of AIF to control inflammation of the pilosebaceous gland, said compositions it should be able to be used in treating in addition to Acne Vulgaris and to Folliculitis, related skin disorders in mammalian skin and scalp, such as acne rosacea, seborrhea, impetigo or psoriasis.

[0031] The present invention thus consists in compositions for the treatment of pilosebaceous gland inflammations, comprising as active ingredient AIF (as herein defined) or chemical compounds which finally release AIF, or combinations of aluminium and fluoride salts which finally release AIF.

[0032] The composition according to the present invention suitably comprises AIF at a concentration from 0.0001-50.0%, preferably between 0.001-5%; advantageously between 0.05-1.0% by weight.

[0033] The pilosebaceous gland inflammations to be treated by the composition according the present invention are preferably Acne Vulgaris and Folliculitis.

[0034] The composition according to the present invention may comprise also additional pharmaceutically and/or cosmetically acceptable compounds and/or compositions. It is thus to be understood that all the additional compounds and/or compositions mentioned below have to be acceptable.

[0035] The active agents may be formulated into various pharmaceutically and/or cosmetically compositions, e.g. a solution, a lotion, a tonic, a shampoo, a gel, a mousse, a wax, a stick, a mask, a soap, a moisturizer, a powder, a perfume, a dye, a brilliantine an aerosol, a pomade, a cream, an ointment, a paste, a systemic capsule or tablet.

EXAMPLE 1

[0087] An Acne Vulgaris (FIGS. 1a, 1 b and 1 c) inflammatory lesion on the right cheek of a 12 yrs old subject was treated by AIF trihydrate at 0.5% concentration dissolved in water only. The subject applied each 3-4 h the solution as a spray. Pictures were performed in a room with artificial constant light by a Sony Mavica FD95 digital camera at a resolution of 1600×1200 pixels. The figures demonstrate rapid fading of the papule at 14 h from start of treatment and its final resolution at 26 h.

[0088] Area of inflammation was measured by image analysis techniques as follows:

[0089] Pictures (FIGS. 1a, 1 b and 1 c) were saved as a BMP file and loaded into Scion Imaging software v. 4.02 (NIH, USA). All three pictures were concomitantly analyzed on the same frame. First, pictures in gray scale were smoothed, manually thresholded, turned into a binary picture and the results transformed to an outline filter. The area of each outlined papule was measured by the software (n=3) and data was further plotted and statistically analyzed by student's t-test in FIG. 2 (Sigmaplot, Jandel, Java). The results (FIG. 2) demonstrate that application of AIF heals the inflamed papule within about 24 h (p<0.01 at 14 h and at 26 h). Any artisan in the art will recognize the surprising healing process of the papule within one day.

EXAMPLE 2

[0090] A Folliculitis (FIGS. 3a, 3 b and 3 c) inflammatory lesion on the left posterior thigh a 43 of a 43 yrs old subject was treated by AIF trihydrate at 0.5% concentration dissolved in water only. The subject applied each 3-4 h the solution as a spray. Pictures were performed in a room with artificial constant light by a Sony Mavica FD95 digital camera at a resolution of 1600×1200 pixels. FIGS. 3a, 3 b and 3 c demonstrate rapid fading of the papule at 10 h from start of treatment and its final resolution at 18 h.

[0091] Area of inflammation was measured by image analysis techniques as follows:

[0092] Pictures (FIGS. 3a, 3 b and 3 c) were saved as a BMP file and loaded into Scion Imaging software v. 4.02 (NIH, USA). All three pictures were concomitantly analyzed on the same frame. First, pictures in gray scale were smoothed, manually thresholded, turned into a binary picture and the results transformed to an outline filter. The area of each outlined papule was measured by the software (n=3) and data was further plotted and statistically analyzed by student's t-test in FIG. 4 (Sigmaplot, Jandel, Java). The results (FIG. 4) demonstrate that application of AIF heals the inflamed papule within about 18 h (p<0.01 at 10 h and p<0.001 at 18 h). Any artisan in the art will recognize the surprising healing process of the papule within less than one day.

EXAMPLE 11

[0144] A 22 years old woman with severe cystic acne was treated for 12 weeks with aluminium fluoride cream at 0.20 g % concentration, in a cream containing sulfur, resorcinol and clindamycin. In the past, she did not respond to classical topicals, such as benzoyl peroxide, antimicrobials and topical retinoids or to systemic antibiotic treatment. The subject applied the cream thrice daily for the first 6 weeks and twice daily afterwards. Results are shown in the enclosed FIGS. 5a, 5 b and 5 c and demonstrate gradual and complete disappearance of lesions after 4 months of treatment. It is obvious for a skilled artisan in the acne treatments that the results are beyond any improvement a common topical can achieve.

EXAMPLE 12

[0145] A 15 yrs old student, with mild acne, and previous antimicrobials and benzoyl peroxide treatment. The subject was instructed to apply twice daily a 0.15 g % of an aluminium fluoride cream with sulfur and resorcin. Results are shown in enclosed FIGS. 6a, and 6 b and demonstrate gradual and complete disappearance of lesions after 3 months of treatment.

EXAMPLE 13

[0146] Subjects suffering from mild to severe Acne Vulgaris were treated with an anti acne cream containing aluminum fluoride at 0.5% with sulfur, resorcinol and clindamycin. Most of the patients were previously treated with either topical antiobiotics, benzoyl peroxide and/or systemic teracyclines. No other antiacne drugs were used during the treatment period. Each subject applied the cream twice daily for 4-8 weeks. Subjects were photoed before and after treatment with a Sony Mavica FD95 digital camera at a resolution of 1600×1200 pixels.

[0147] Inflammatory lesions were counted on the face (forehead or cheek, n=14 subjects, upper figure) and back (n=6 subjects, lower figure). Comparison between mean number of lesions pre and post treatment are shown in enclosed FIGS. 7a and 7 b and demonstrate unprecedented accelerated disappearance of inflammatory lesions at 4 weeks from start of treatment, already. The mean number of lesions decreased from 8.8 4 to 1.6 0.9 on one aspect of the face (p<0.001, paired t test) and from 11.8 3.3 to 2.5 1.4 on back (p<0.001, paired t test).
